Contact UsA current sensor is a device that detects and converts current to an easily measured output voltage, which is proportional to the current through the measured path. There are a wide variety of sensors, and each sensor is suitable for a specific current range and environmental condition. No one sensor is optimum for all applications.
There are a variety of current sensing technologies that can monitor the status of an HEV or EV battery. The solution varies with the voltage and capacity of the battery. As shown in Figure 1, there are two main locations where you can measure current: top of stack (high-side sensing) and bottom of stack (low-side sensing). Figure 1.
Current sensing is a fundamental requirement in a wide range of electronic applications. Motor speed controls and overload protection This application note focuses on the concepts and fundamentals of current sensing circuits.
Typical monitoring circuits consist of a shunt resistor in series with the system load. The voltage drop across this shunt resistor in indicative of the load current. The signal from the shunt resistor gets amplified and converted to digital signal before being fed to the microcontroller (MCU).
As shown in Figure 1, low-side current sensing connects the sensing resistor between the load and ground. Normally, the sensed voltage signal (VSEN = ISEN × RSEN) is so small that it needs to be amplified by subsequent op amp circuits (e.g., non-inverting amplifier) to get the measurable output voltage (VOUT). FIGURE 1: Low-Side Current Sensing.
No one sensor is optimum for all applications. Among these sensors, a current sensing resistor is the most commonly used. It can be considered a current-to-voltage converter, where inserting a resistor into the current path, the current is converted to voltage in a linear way of V = I × R. Power loss since power dissipation P = I2× R.
